Answer:
[tex](6x^{4} + 2x^{3} -4x^{2}+ 10x + 8)[/tex]
Step-by-step explanation:
Given equation as :
[tex](15x^{4} + 2x^{3} - x^{2} + 8x -5 ) - (9x^{4} + 3x^{2} - 2x - 13)[/tex]
Or, [tex](15x^{4}- 9x^{4})+ 2x^{3} + ( - x^{2} -3x^{2}) + (8x + 2x)+ (-5+13)[/tex]
[tex](6x^{4} + 2x^{3} -4x^{2}+ 10x + 8)[/tex] Answer
